Las emisiones de United Aerolíneas alcanzan su máximo después de 2019 y es probable que sigan aumentando

Key Points

• United Airlines' greenhouse gas emissions in 2024 reached their highest level since 2019 and are expected to rise further due to fleet growth and limited sustainable fuel supply.
• The airline is investing in newer, more efficient aircraft and increasing its use of sustainable aviation fuel (SAF), but supply constraints and changing U.S. tax credits pose challenges.
• United's new premium-heavy cabin layouts may increase emissions per traveler despite overall aircraft efficiency gains.

Summary

United Airlines' greenhouse gas emissions climbed in 2024 to their highest point since 2019, driven by a growing fleet and limited availability of sustainable aviation fuel (SAF). The airline is expanding its use of newer, more efficient aircraft and increasing SAF adoption, but ongoing supply issues and recent reductions in U.S. SAF tax credits complicate efforts. Additionally, United's shift to more premium cabin layouts could raise emissions per traveler, even as the airline works toward long-term net zero goals.
